When is the value of van't Hoff factor more than one?

Explanation

To determine when the value of van't Hoff factor (i) is more than one, we can follow these steps:

### Step 1: Understand the van't Hoff factor (i)
The van't Hoff factor (i) is a measure of the degree of dissociation or association of a solute in a solution. It is defined as the ratio of the number of particles in solution after dissociation or association to the number of formula units of the solute initially dissolved.

### Step 2: Identify the conditions for dissociation
When a solute dissociates in solution, it breaks down into multiple particles. For example, when an electrolyte like sodium chloride (NaCl) dissolves in water, it dissociates into two ions: Na⁺ and Cl⁻. In this case, the van't Hoff factor (i) is equal to the number of ions produced from the dissociation.
